Good choice if you aren't used to this size of boat. The Morgan 49 O/I is a big old tub that will handle the weather fine and take a while to wind up to hull speed (i.e. she won't likely get "away" from you). Big mainsail though: you'll enjoy jumping the halyard with all your weight. I'll bet she tracks well with a fingertip at the wheel, however.
I would let the skipper dock and moor, however...the "way on" with near 50,000 of boat (loaded with amenities, I would imagine!) can be extremely deceptive. Mine's 30,000 lbs., and coming from a 9,000 lb. boat only seven feet shorter, I had to relearn docking all over again.
